Grand River Watershed-Wide Wastewater Optimization Pilot Project Workshop #3 The third and final workshop of the pilot project was held on February 22 nd , 2011 at the Jarvis Community Centre in Haldimand County. Excluding GRCA staff, 23 participants attended the workshop representing 7 of the 11 watershed municipalities. Councillor Lorne Boyko of Haldimand County welcomed workshop participants on behalf of the County. The workshop provided a forum for reporting the results of the take-away assignments from the first two workshops. The report-outs were requested in a PowerPoint format consisting of: A system description, including the population served, type of WWTP, monitoring frequency, hours of operation, etc. An aerial photograph of the WWTP showing the layout of the unit processes; Trend graphs of monthly average flows (with the nominal design flow), raw sewage concentrations and effluent concentrations (with objectives and C of A requirements) for the 12-month period Aug 2009 to July 2010, A summary table comparing per capita flows, BOD 5 , TSS and TKN loadings and ratios (peak day flow to annual average flow, raw TSS/BOD 5 and raw TKN/BOD 5 ); Where applicable, the results of a sludge accountability analysis comparing reported sludge production to projected sludge production for the 12-month reporting period; A Performance Potential Graph identifying the estimated capacities of each of the WWTP’s major unit process and comparing these rated capacities to the current annual average flow and the nominal design flow. A summary of the results from the survey, as well as personal findings or discoveries from those participating in the surveys. Table 8 is a summary of the report-outs presented at Workshop #3. 21 | Page

Workshop participants were asked for comments and suggestions for follow-up optimization activities. Appendix E contains a summary of the participant feedback and suggestions for follow-up. The comments and suggestions from the participants were brought forward to the Steering Committee for their consideration in developing future optimization activities within the watershed. Communication and Outreach A communications plan for the WWOP was developed and implemented. Communication elements delivered included: A report to the GRCA board (June 10 th , 2010) to introduce the project and invite municipal participation; 22 | Page
